Description

[Detailed Description of the Invention] This invention relates to a waterproof case for a fuse used in a fuse connection that requires waterproofing.

BACKGROUND OF THE INVENTION Conventionally, fuse connections in motorcycles are usually made in a fuse holder having a structure as shown in FIG. This fuse holder is constructed by connecting a holder body 1 and a lid body 2 with a hinge, and has recesses 1a and 2a in each of the holder body 1 and lid body 2 to accommodate a fuse 3, and the recess 1a on the holder body 1 side is provided with recesses 1a and 2a, respectively. A clip-on terminal 5 to which a cord 4 is connected is attached, and the cord 4 is pulled out from the grooves 1b and 2b at both ends. In this conventional fuse holder, it is necessary to provide some allowance for the wiring for wiring work or maintenance purposes, and this allowance causes slack in the wiring, which impairs the appearance. Also, although the spare fuse is installed in a separate location, it is necessary to consider the waterproofing of this spare fuse.
Also, since it is attached separately, it is inconvenient to handle when replacing the fuse.

In addition, as another conventional example, a structure shown in Japanese Utility Model Application Publication No. 53-155029 has been proposed;
Even in this proposal, the drawbacks mentioned above remain.

This idea was made to eliminate the above-mentioned drawbacks of the conventional method.It improves the appearance without exposing the slack in the wiring, and also waterproofs the spare fuse.
Another object of the present invention is to provide a waterproof case for a fuse that can be easily handled when replacing the fuse.

An embodiment of the present invention will be described below with reference to the drawings.

The fuse waterproof case of the embodiment is used for the fuse connection part of a tricycle as shown in FIGS. 2 and 3, and this fuse waterproof case 10
is arranged below the seat 11.

As shown in FIGS. 4 to 6, this waterproof fuse case 10 consists of a cylindrical case body 12 with an open bottom and a cylindrical lid body 13 with a bottom, which is also open on one side. Inside, there are a fuse support member storage part A that stores a fuse support member that supports the fuse 14 and the cords 15a and 15b in a connected state, that is, a fuse holder 16, and a spare fuse storage part B that stores a spare fuse 17. , a cord 1 extending from the fuse holder 16
A cord storage part C is provided to store the slack of one of the cords 5a and 15b, and further,
Cord 15a, 1 extending from fuse holder 16
Cord insertion holes 12a, 13 for pulling out 5b to the outside
a is provided at the bottom of the case body 12 and the lid 13, respectively.

The case body 12 and the lid body 13 are shown in FIG.
As shown in FIG. 6, the case body 12 has an approximately elliptical cross-sectional shape with a slightly tapered end, the inner diameter of the opening edge 12b of the case body 12 is slightly increased, and a circumferential groove 12c is formed on the inner circumferential surface of the case body 12. On the other hand, a protrusion 13c extending over the entire circumference is provided on the outer periphery of the opening edge 13b of the lid body 13.
is formed, and the opening edge 13b of the lid body 13 and the opening edge 12b of the case body 12 are tightly fitted, thereby achieving waterproofing together with the effect of the engagement between the protrusion 13c and the circumferential groove 12c. Moreover, the lid body 13 is prevented from coming off.

Furthermore, a cylindrical preliminary fuse support hole 13d into which one end of the preliminary fuse 17 is inserted and supported is provided inside the lid body 13. The case body 12 is provided with a drain hole 12d. The water drain hole 12d drains water droplets generated due to condensation within the waterproof case 10. Note that the case body 12 is formed with a mounting portion 18 for attaching to the vehicle body.

Although the structure of the fuse holder 16 is not particularly limited, the fuse holder 16 of the embodiment is similar to the conventional fuse holder shown in FIG. 16c
), a snap-on terminal 16b is attached to the holder main body 116a, and the cords 15a and 15b are connected to this terminal 16b, respectively.
In addition, adhesive is applied to the pull-out part (arrow A) of the cord 15b from the cord insertion hole 12a on the side with the slack part, which prevents the slack part of the cord 15b from coming out and prevents the cord from being inserted. Hole 1
Prevents water from entering from 2a.

In the embodiment, the cord storage section C is provided only for the cord 15b on one side, but it is also possible to provide dedicated or common cord storage sections for the cords on both sides.

Furthermore, a tape 19 may be wrapped around the cord 15a and the tape 19 may be brought into contact with the inner surface of the case body 12 to prevent the cord 15b from shifting when an external force is applied (see FIG. 4). reference).

In addition, in the embodiment, the case body 12, the lid body 13
Both are cylindrical in shape, but they can also be split vertically into two, with one half serving as the case body and the other serving as the lid body, and the two being connected by a hinge.

As explained above, the waterproof fuse case of the present invention is equipped with a cord storage part that stores the slack of the cord, so unlike the conventional case where the slack of the cord is visible from the outside, it does not spoil the appearance. Moreover, since it is provided with a spare fuse storage section for storing a spare fuse, it is easy to handle when replacing the fuse, and the spare fuse can be waterproofed at the same time, which is efficient. Furthermore, since the fuse is housed in a fuse support member, and this fuse support member is housed in a waterproof case for the fuse, the fuse connection part is more reliably waterproofed. Since the slack part is inside the fuse waterproof case, there is no problem with maintenance even if the cord pull-out part is glued, and it is possible to further improve waterproofness, which provides various excellent effects. It is something to play.
